Does humidity cause wood swelling?

Does humidity cause wood swelling?

Shrinking and swelling occur as the wood changes moisture content in response to daily as well as seasonal changes in the relative humidity of the atmosphere, i.e., when the air is humid, wood adsorbs moisture and swells; when the air is dry, wood loses moisture and shrinks.

Does humidity ruin wood furniture?

A poor balance of humidity in your home has the potential to destroy your wood furniture. When exposed to an excessive amount of humidity, the wood furniture can expand and begin to deteriorate. High levels of humidity are most frequently observed in the spring and summer time.

Does humidity affect wood?

All wood is hygroscopic, meaning that when exposed to air, it will release or pick up moisture until it reaches equilibrium with the humidity in the air. Because of this fact all wood will expand as it gains moisture and will shrink when it loses moisture. Wood also does not shrink or swell equally in all directions.

Does moisture make wood expand?

On the average, wood gains or loses about 1 percent moisture content for every 5 percent change in the relative humidity. The wood fibers swell as they absorb moisture and shrink as they release it, causing the wood to expand and contract.
